Printing apparatus and control method

A printing apparatus comprising:

• a conveyance unit including a first conveyance member that conveys a print medium in a conveyance direction and a second conveyance member that is disposed downstream of the first conveyance member in the conveyance direction and conveys the print medium in the conveyance direction;
• a printing unit located between the first conveyance member and the second conveyance member in the conveyance direction and having a printing element array being a plurality of printing elements that are arrayed in the conveyance direction and apply a print material onto the print medium conveyed by the conveyance unit;
• an obtaining unit that obtains information indicating a type of the print medium;
• and
• a control unit that controls the conveyance unit and the printing unit so as to print an image onto the print medium by performing a printing scan in which the printing unit is caused to apply the print material while being scanned in a direction crossing the conveyance direction, and a conveyance operation in which the conveyance unit is caused to convey the print medium in the conveyance direction,
• wherein the control unit controls the printing unit such that, in a case where the information obtained by the obtaining unit indicates board paper and an image is to be printed onto the print medium in a state where the print medium is supported by the first conveyance member and not supported by the second conveyance member, the printing unit uses a printing element included in a first region and does not use a printing element included in a second region located downstream of the first region in the conveyance direction.

• a printing unit located between the first conveyance member and the second conveyance member in the conveyance direction and having a printing element array being a plurality of printing elements that are arrayed in the conveyance direction and apply a print material onto the print medium conveyed by the conveyance unit;
• a platen disposed between the first conveyance member and the second conveyance member in the conveyance direction at a position lower than the first conveyance member in a height direction perpendicular to a surface where the printing elements are arrayed, and supporting the print medium from below;
• and
• a control unit that controls the conveyance unit and the printing unit so as to print an image onto the print medium by performing a printing scan in which the printing unit is caused to apply the print material while being scanned in a direction crossing the conveyance direction, and a conveyance operation in which the conveyance unit is caused to convey the print medium in the conveyance direction,
• wherein the control unit controls the printing unit such that, in a case where an image is to be printed onto a print medium of a first type in a state in which the print medium of the first type is supported by the first conveyance member and not supported by the second conveyance member, the printing unit uses a printing element included in a first region and does not use a printing element included in a second region located downstream of the first region in the conveyance direction.
